Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

Connecting the wires

We now have two completely functional windows in our application. But we need to create some sort of navigation bridge in order for our users to navigate from one window to the next. While we are at it, we will give users the ability to manually refresh the list as their geographic location might change while using the application.

Selecting a photo

The very first thing we will do is to load the PhotoViewerWindow module from our main window. To do this, we will add the following line at the very top of the ApplicationWindow.js file:

var PhotoViewerWindow = require('PhotoViewerWindow');

To open the photo viewer window when the user selects a photo from the list; we will add an event handler to our ListView object. When the itemclick event is triggered, we will create a new instance of the PhotoViewerWindow class by passing it the itemId event from the selected row. We will then open our newly created window:

listView.addEventListener('itemclick', function(e){
  var photoWin...
